This invention relates forging machines and is designed'pri-marily as an improvement upon machines of that type shown inwarious patents issued to me as for example, Patent, No. 1,399,850'of December 13, 1921 and Patent No. 1,382,625 dated June 28, 1921.

' In forging machines of this type there has been used a gripping slide provided with an extension for engagement with a. bearin whereb the slide hasbeen properl guide been found, liowever,-that t e extension andbearing of this slide have been so located that scaleand water dropping elf of the gripping dies hasfallen onto the extension with the result that the scale and dirt has worked (guickly into the bearings of the slide and ma it extremely difiicult to keep these'beari'ngs in proper, condition.- As the bearings become worn the gripping slide ,39 tion of thefaultsheretofore present in machines of this type. With the foregoing and other objects view which will appear as the. description proceeds, the invention resides in the combi- 35 nation and arrangement of parts and in the details of construction hereinafter described 1 and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be madew-ithin the scope 4'0 of what is claimed, without departing from the spirit of the invention.

In the -accompanying'drawings the]: preferred form of the invention has-been shown."

the heading slide 3 is mounted for 'reciprocation, any suitable means such as a crank 4 and pitman 5 bein used for actuating this slide; Another ui' eway 6 is provided with. 1n the bed or y 1 and a plunger 7 is mount-' 00" ed for reciprocation therein, this plunger beingoperated by an eccentric8 orany other suitable means carried by the shaft 9. z The guideways 2 and 6 communicate at one end with a transverse re'ess 10 at one end-v 65 "of which is located a shoulder 11 for supportmg a stationary gripping die 12. The bottom of the recess 10 1s extended downwardly be neatl'i the she der. 11 and said recess opens through one slde of the bed or body 1 as '70- shown at 13, this end of the recess be provided with bearings 14 located latera y be- 'yond the stationary gripping die 12 and ing the bed or body 1. Olgviously the construction of the bearings can be varied to suit the manufacturer and the user, it merely beso ing essential thatthey serve to support the gm ping'slide in proper working position 'w' recess 10. This gripping slide is 1 adapted to reciprocate transversely of, the bed or body 1, motion being transmitted 85, thereto in the present instance from" the plunger 7 through a pitman;17:connected to ato'figle 18. N f

T egripping slide hasan extension 19 projecting from the bottom thereof and'so shaped asto work freely withinthe lower portion .of the recess 10 and under the shoul-' er 11. The free endportion of thisextension is projected upwardlyand terminates in a'bea-ring head 20 havinglaterally extending flanges 21 adapted'to slide upon the bearings 14. It will be noted by referring particularly to'Figure 2 that the engaging bearing surfaces formed by the bearings 14 and the ribs 21 are located well above the middle 1 portion of the extension 19.

' It is to be understood of course that a grip ping die 22 is to be carried by the gripping slide so as to cooperatewith the die 12 in the usual way. 5

It is believed that the advantages result in from the use of this im roved machine 1 be apparent. During the operation of the machine it is customary to supply water thereto. The constant action of the gripping dies uponithe work therebetween produces scale which is washed downwardly by the water and, as before explained, has heretofore tended to work into the bearings of, the

gripping slide andnot only interfere with the'proper operation of the slide but also to produce an'undesirable wear thereon which as soon resulted in .disalinement of the dies; With the present structure, however, the use of a dro extension 19- with elevated bearings obviates this fault. It becomes impossible for the scale or other dirt to work upwardly to the bearings 14 and, consequently,

, the objectionable features heretofore pointed out are completely eliminated and proper alinement of the dies is maintained.

\Vhat is claimed is:

1. In a machine of the class described the combination with a bed, a heading slide, and 'algripping die, of a gripping slide, an extension upon the slide projecting under the gripping die, and a bearingcarried by the extension, said bearing being above the level of the extension.

2. In a machine of the class described a.

heading slide, a gripping die, a gripping slide, and bearings for the gripping slide (115- posed at a level above the bottom of the gripping die, said gripping die being disposed between said bearin s and the gripping slide.

3. A machine of t 1e class described including agripping die, a gripping slide, an extension upon the slide adapted to work beneath the gripping die, and bearings jor the gripping slide and the extension, said bearings being located above the level of an intermediate portion of the extension.

4:. In a machine ofthe' class described, a gripping die, a gripping slide, an extension upon the slide having an intermediate por- WILLIAM L. CLOUSE.
